Re: Heater work when switch to fan on but doesnt work...

When switched to on does it make heat or is ir just the fan blowing? Take the first cover off the thermostat and see if there is a jumper wire from RC to RH. If not you need to add one. Also, the heat doesn't come on instantly like the A/C, it takes a couple of minutes for the pilot to lite, the burners to come on and then the time/temp delay relay will click on the fan motor, this may take a few minutes.

Hi: I have an bathroom heater fan, Thermosafe model:3208,(new Zealand) one day i found out that i could not turn it on, it even not make the "clip" sound (this heater wasn't designed...

From your description, it sounds like the pull chain ON/OFF switch is broken.Admittedly, this is the first time I have ever heard of a pull chain switch being on an electric heater, But, I guess it is in the ceiling and not wired to a wall switch, it's the only way to turn it ON or OFF. I wouldn't think that replacing the pull chain switch would be that difficult or expensive to replace. Most home centers and hardware stores sell this type of switch for use in ceiling fans, The key would be removing the faulty switch and taking it with you to buy a new one. You want to be sure that the new switch matches the amperage and polarity of the old switch.

As far as the unit only being a year old and the switch failing so quickly ... it's in a warm moist environment 24 hours a day. It doesn't surprise me that the switch broke. You might want to consider replacing the pull chain switch with a hard wired wall switch. Certainly, it would cost more than replacing the pull chain switch, but you'd never have that problem again.

I hope this helped you, Mary. Please let me know.

I have an evaportating cooler omega it only works on fan.

I would have the unit looked at. The auto section on the motor is turned on by the cooler automatically so there seems to be a problem there at that switch.

Good Luck on your repairs hope this helped some

Blower fan will not come on when set on Auto in heat mode.

the fan is controlled by a fan center or a stack switch. as burners light and heat up the spring sensor on the bulkhead above burners heats up and turns and a a point energizes the indoor fan if it gets to hot the burners go out on safty. sounds like a fan control is bad tap on them gently and they sometimes break loose but if not then have a pro replace fan control and test heat exchanger.

you either have a wrong connection or a defective thermostat.

the fan when switch to auto will run as the heater or ac is running and when in the "on " position, it will always run.

there is a problem in the connection of the cool or heat contact to the fan relay that is why it is not running if you place it on auto.

trace the diagram of the thermostat and you would know where the problem is...

i hope i ws able to solve ur problem..

pls rate me

tnx 4 using fixya..
